What is aNeodymium Magnet?

- Oct 24, 2017 -

NdFeB, in simple terms is a magnet, and we usually see the magnet is different, because of its excellent magnetic properties known as the "magnetic king." NdFeB contains a large number of rare earth elements neodymium, as well as iron and boron, its characteristics of hard and brittle.

As the surface can easily be oxidized corrosion, NdFeB must be surface coating treatment. Surface chemistry passivation is one of the best solutions.

NdFeB as a rare earth permanent magnet material has a very high magnetic energy product and coercivity, while the advantages of high energy density NdFeB permanent magnet materials in modern industry and electronic technology has been widely used, so that the instrument It is possible to miniaturize, reduce, and reduce the size of the equipment such as an instrument, an electro-acoustic motor, and a magnetic magnetization.

NdFeB has the advantages of high cost performance and good mechanical properties. The disadvantage is that the working temperature is low, the temperature characteristics are poor, and it is easy to be pulverized and corroded. It must be improved by adjusting its chemical composition and adopting surface treatment method. To meet the practical application requirements.

NdFeB magnetic materials, as the latest results of the development of rare earth permanent magnetic materials, because of its excellent magnetic properties and is known as "magnetic king". NdFeB magnetic material is praseodymium neodymium metal, boron iron and other alloys. Also known as magnet steel.
